Raydium in one paragraph
Raydium is an automated market maker: a smart contract holding two piles of tokens, RUECAT on one side and SOL or USDC on the other. There is no order book and no counterparty — the pool quotes a price from the ratio between the two piles, and every trade shifts that ratio slightly. Buying directly on Raydium is useful when you want to see exactly which pool your order touches.
Step-by-step purchase
Go to raydium.io, open the Swap tab and connect your Solana wallet. Choose SOL or USDC as the input token, then paste the official RUECAT contract address in the output field and select the token that appears.
Open the settings gear and set slippage tolerance. One percent works for a calm market; volatile launches may need two or three. Enter your amount and read the details panel: minimum received, price impact and the pool fee, which is normally 0.25 percent on standard pools.
Click Swap, confirm in your wallet, and wait for the confirmation toast. Your RUECAT balance updates immediately and the transaction is permanently visible on Solscan.
Reading price impact like a professional
Price impact tells you how much your own order moves the pool. A 0.2 percent impact means you barely disturbed the market. A 6 percent impact means you paid a 6 percent premium and will likely see the chart wick on your own candle. In thin pools, splitting one large order into four smaller ones over a few minutes typically saves more than any fee optimisation.
Always check pool liquidity before buying. As a rule of thumb, keep any single order below 1 percent of the pool's total liquidity if you want a clean fill.
Raydium or Jupiter?
If you simply want the best available price, use Jupiter — it compares Raydium against every other venue and often splits the route. Use Raydium directly when you specifically want a single known pool, when you are providing liquidity, or when an aggregator route is failing repeatedly.
